Application filed June 20, 1914. Serial No. 846,334.

To all whom it may concern:

Be it known that I, FRED F. BURDICK, a citizen of the United States, and a resident of Milton, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Collapsible Cabinets, of which the following is a specification.

This invention relates to cabinets which are used for giving steam, light and other baths; and which are adapted for continuous or intermittent use; and which, when not in use can be collapsed, as it is termed, for storage or shipping.

The principal objects of the invention are to obtain a collapsible cabinet, provide with sheet metal panels and corners, which can be opened to an operative condition by a person manipulating but few of the parts thereof, without said person being required to move from a given position; and if open, can be clsoed in the same manner; to obtain a cabinet which is simple in construction, not liable to break or get out of order; and one which, when closed, can be stored or shipped without liability of breakage.

A further object is to obtain a cabinet of the kind named which operates, in the opening and closing thereof, in such manner as to be readily understood by a person not particularly skilled in mechanics.

Additional objects are set forth in this specification and in the claims.

I have illustrated a collapsible cabinet embodying this invention in the drawings accompanying and forming a part hereof, in which Figure 1 is a perspective of the device, in an operative condition. Fig. 2 is a perspective of said device in a closed condition. Fig. 3 is a side elevation of a modification of the device in a substantially closed condition. Fig. 4 is a side elevation of said modification with the parts thereof in a different position from that shown in Fig. 3: and Fig. 5 is a side elevation of said modification with said parts in a nearly opened condition.

The modification illustrated in Figs. 3, 4 and 5, consists in a construction which gives a shorter front than back, with a corresponding change to the sides, when the device is in an operative condition; while in the construction illustrated in Figs. 1 and 2 the front and back are substantially the same. height.

doorway the cabinet, and to be A reference character applied to designate a given part 1nd1cates said part throughout the several figures of the drawing, wherever the same appears.

A is the front of the cabinet, and is illustrated as consisting of a sheet metal panel, attached at its side edges to corner pieces 1).

Front A is provided with an opening or and a is'a door adapted to be opened, on hinges B, to admit a person to closed to close said door way or opening. 6 is a latch to door a. The cabinet back is a sheet metal panel, attached to the rear corner posts 1) at its edges, in the same manner as is the front panel A, and is a substantial duplicate of said front panel, with the exception that there is no opening or door way thereto and no door thereon. The door a is provided with an aperture therethrough which is illustrated in Fig. 1, with a panel, say of glass, covering said aperture, and lettered (J.

' he sides of the cabinet, are substantially duplicates, but rights and lefts, and consist of parts 6, e, which are hinged together by hinges f, and to the corner pieces D by hinges F.

G is the top of the cabinet, and consists of the part 9 which is rigidly secured to the rear corner pieces and to the back, and the part 9' which is hinged to part 9 by hinges h, the hinged door 9 and the movable slide G Slide G is provided with the aperture H, through which the head of the person using the cabinet may protrude.

The mechanism by means of which the opening of the cabinet from a closed position, or vice versa, is elfected, comprises the several levers hereinafter described, which are attached to the corners D, the top G, and to each other, as follows: I, I J are links, J is a lever, and said links and lever are pivotally attached to corners D by pivots 2', and j, respectively, and to each other by pivots i and j K is a connecting tie rod, pivoted at its ends on pivots and j It is to be observed that lever J is provided with a long member, of substantially the same length as are links I, 1 and J, and with a short member, which is at substantially right angles to the long member. The top G and lever J are connected by a two part link, having one of said parts, (m) attached to the end of said short member of lever J by pivot N, and the other of its tion, it is first stood parts (m attached to top G by pivot n. Parts m, m are connected together by pivot Z.

The use of this cabinet, when set up, as in Fig. l of the drawings, is well known to the medical profession, and requires no de scription herein; nor is it necessary to describe the function or use of the electric conductors X, which are illustrated.

The modified construction which is illus trated in Figs. 3, 4L and 5, consists merely in shortening the front ones of the corners D, (lettered D in said figures), and the corresponding cutting off of the tops of the side panels 6, e. The resultof this modification is that when the cabinet is in operative condition the top is inclined, instead of being in a horizontal plane, as is the case in the construction which is illustrated and 2.

The operation of the several mechanisms which form the essential embodiment of this invention is the same in all the constructions shown.

With the cabinet closed and lying down, as in Fig. 2, to put it in an operative condion end, as in Fig. 3. The top G is then raised to straighten out the two part link m, m In Fig. 4 said top is shown as partially raised, and with said link partially straightened; the parts m and m being at an angle of more than ninety degrees to each other. The cover is to be continuously raised until the parts m, m are in a straight line. After said parts are in line said top G is lowered, being forced down, if required; thereby turning bell crank lever J 1 on its pivot y. Lever J being tied to link J, (by pivot f and to levers I, P, (by connection K), said links are also turned on their respective pivots, and the front and rear corners D are forced apart. Corners D moving apart, as above, draw panels 6 of sidesE from the position where they are shown in Figs. 2 and 3, (where they are in nearly parallel planes), through the position thereof which is illustrated in Fig. 5, into the position which is illustrated in Fig. 1. The cabinet can then be used as an ordinary cabinet of this kind.

To close the cabinet, that is to put it into condition for storage or shipment, the top G is raised until the front and rear corners D are brought adjacent to each other, with the panels 6 in nearly parallel planes, the joint of parts m, m at pivot Z, is broken and the top is lowered into the position which is illustrated in Figs. 2 and 3. r

Y is a latch which looks the front and rear corners D together, by turning it on pivot y and engaging it with pivot y as in Fig. 2.
